I'm testing jojaba oil on the inside of a lock right now. It's about time to check it again. I have not used it for ball lube (preferring either homemade or spit and because I have not tested it in the various mixtures). But when I put my smoothbore away in mid Nov. I checked the inside of the lock and the jajoba from the summer was still doing its job (no rust, parts working smoothly).
The whales are being killed for their meat. The oil is a byproduct IMO.
Interesting, I put a rifle, my .69 (caplock) away for some 8 or 9 years, unfired or touched, for that length of time. Is that a 'test' of oil?
I'd cleaned the bore normally after shooting one day, by dunking the barrel's breech in a bucket of cold water and flushing water in and out until I decided it was clean, then dried it with 5 or 6 heavy cotton patches, then sprayed WD40 into the bore until it ran out the nipple seat, then ran a dry patch up and down the bore with force, to blast out the excess WD40, then replaced the nipple, then wiped the lock off with a WD40's patch, then stored the gun as noted above - 8 or 9 years, muzzle down. After that period of time, stored in my basement for at least 4 years and Brad's basement, butt down for another 4, maybe 5 years until we took it to the range to shoot (first and only for him) the first time in that length of time. It was then cleaned as usual and stored for another year, then he sold it back to me. No rust inside the lock, which had never been off for cleaning (initially lubed with Amsoil 100:1 2 stroke oil) no rust inside or outside the barrel. It had only ever been wiped down with a WD40 patch on the outside and WD40'd inside.
The humidity here runs about 30% to almost 100% with a yearly average of about 50%, which makes wood stored outside level out at about 9% moisture, which is perfect for making bows. The humidity inside my house is usually in the lower ranges, probably around 40% (a guess), unless humidifiers are used to artificially increase humidity.
I can bring in a flinter with lots of black (wet) fouling on the outside of the lock, barrel breech and pan, and in 2 hours, it's bone white and bone dry. That's when the humidity is higher than 80% outside.
Humidity in the stored area is VERY important consideration to the preservatives used.
